Since Kayfun have upgraded to include an O-ring in the filling hole, (in the Lite+,) the two have equal pros and cons, in my opinion. My R91 did leak juice out of the filling hole when I left it full for a week or two. I like it though. Definitely a cleaner flavor than a Protank II, which is in turn better than an EVOD.

I'd be cautious about doing that. Those things are precision engineered; if the juice channels are too deep or too shallow the vape will not be the same.The things that guy in your video was saying just don't apply to the real things.

Assuage your temptation with a Nautilus or Aerotank and a good rebuildable dripping atomiser, and put the R91 on your birthday list. That way you can play with airflow, coils and wicks before it arrives.
